INCANDESCENT GAS-BURNER. 1

Specification of Letters Patent.

Patented Nov. 26, 1912.

Application filed November 29, 1911. Serial No. 663,084.

To all whom it may concern:

Be it known that I, J AOQUES Vrssnnux, a citizen of the French Republic,and resident of 87-89 Quai Pierre-Seize, Lyon, France, have inventedcertain new and use ful Improvements in Incandescent Gas- Burners, ofwhich the following is a specification.

My present invention relates to incandescent gas burners, and relates tomeans for controlling the egress of the gas and air mixture adjacent themantel of the burner.

The principal object of my invention is to regulate the velocity of theflow of the mix ture subsequent to the admission of air with the gas, byresistance to egress of the mixture, and by this arrangement obtain agas of such richness as will produce an incandescent light of thedesired intensity.

It is well-known that the pressure of gas in its conductor, varies andthat a burner in connection with the gas conductor must be regulated toobtain an intensity of light which is neither destructive to the mantelbecause of too much gas, or too little gas. In the event of too muchgas, the flame is not confined within the fabric of the mantel butpasses therethrough and when too small a pressure, there arefluctuations which expand and contract the mantel, which is verydestructive.

The invention regulates the flow of the mixture and not the gas and theair inclependently one from the other.

Other objects of my invention are to provide a simple and efficientdevice of the character described, reducing the number of parts to aminimum and consequently reducing the cost of manufacturing andassembling.

In the drawings, forming a part of this specification :F igure 1 is aside elevation of a burner constructed according to my invention, partsbeing shown in vertical central section to disclose details ofconstruction. Fig. 2 is a detailed view of the upper portion of themixture tube, parts being broken away to disclose details ofconstruction. Fig. 3 is a central vertical sectional view in modifiedform of grate.

Similar characters refer to similar parts throughout the views.

In the drawing, a designates a tubular standard adapted for connectionto the gas fixture or conductor, the lower portion being provided withthe usual gas injector b and the upper margin of the tube a. In otherwords, the grate is provided with apertures which are disposed to directa part of the mixture laterally with respect to the axis of the tube a,as well as substantially parallel with the said axis. I

The tube a is encircled by a collar 6, which may be formed integral witha gallery f for the mantel and globe, this collar being mov-i ablelongitudinally of the tube a and the portion adjacent the upper marginadapted to resist egress of the mixture laterally of the grate d bybeing passed above the margin of the tube a, to deflect the mixtureflowing laterally with respect to the axis of the tube, to a desireddegree. In other words, the collar 6 is adapted to sort of mufiie theegress grate laterally and thus resist flow therefrom to a certaindegree.

The collar is movable longitudinally of the tube by a nut g, which is inthreaded engagement with a threaded portion 2' of the tube a. Asdisclosed in Fig. 1, by this nut g, which may be provided with a handleg to facilitate operation, the collar 6 and gallery are both raised orlowered under control of the nut.

In Fig. 3 of the drawing, a grate d is disclosed as of a hemisphericalor convexo concave shell, with perforations cl, and similar to the flatdrum-like grate disclosed in Figs. 1 and 2, the apertures directing thegas laterally being muflied by raising the collar 6 to lie laterally ofthe grate.

The operation of the device is as follows z-VVhen the gas is admitted tobecome ejected from the ejector 5, air is drawn and mixed with the gasas previously described. The mixture is lighted in any practical manner,and if upon the gas attaining a uniform velocity, the light is not of adesired inten sity, say with too great a flow of gas, the collar 6 israised through nut g and the egress laterally of grate a somewhatmuffled,

If the flow of gas is not sufiicient to provide a light of desiredintensity, the collar 6 is lowered and the resistance to egress isreduced. During operation, the variable resistance to the flow ofmixture regulates the quantity of air drawn through the aperture 0 andno separate device is required at these openings for the regulationthereof.

I claim: ,7

1. In an incandescent gas burner, the combination of a tube forconveying the gas mixture, provided With externally disposed threads, anegress grate projecting fromsaid tube, a collar encircling and movableaxially of said tube to muflie said grate laterally, I and a nut inthreaded engagement with the threads of said tube to operate saidcollar, substantially as and for the purpose set forth.

2. In an incandescent gas burner,t he combination of a tube forconveying the gas mixture, an egress grate projecting from said tuberigidly carried thereby and adapted to deliver gas laterally, a galleryhavlng Copies of this patent may be obtained for a collar formedintegral therewith, encircling and movable axially of said tube, andmeans for retaining said gallery With said collar mufliing said gratelaterally in an adjusted position With respect to said tube,substantially as and for the purpose set forth. i

3. In incandescent gas burners, the combination of a tube for conveyingthe gas mixture, a convexo-concave grate at the end of said tube,rigidly carried thereby, adapted to deliver gas laterally, andprojecting therefrom, and adjustable means for muffling said gratelaterally, substantially as and'for the purpose set forth.

In-testimony whereof I have hereunto set my hand in presence of tWoWitnesses.
